Water Resources Data & Map Viewers
The department manages a variety of critical work through active databases . To promote greater transparency, accountability, and wider access to public information, the department makes interfaces through data and map viewers, available to the public on our website. These interfaces pull information from the same consolidated databases TDEC staff use to keep track of environmental regulatory activities, rosters and status.
Data viewers feature a detailed Help function to assist site users once they are searching within the database. You may also email the TDEC Help Desk at BG-Help_Desk@tn.gov or call (615) 532-0287.

Notes About the Division's Permit Data Viewer:
The Water Resources Permits Data Viewer tool reflects overnight updates posted to the consolidated state database of Water Resources permits. Information in this dynamic database is constantly changing as records are updated daily. Any change made to the permit tracking database should be available to the Data Viewer the next day.
Only the current information shows in the Data Viewer. For instance, a query made yesterday including a data error that gets corrected today will show the corrected value only when the same query is run tomorrow after the update has been completed. Historical information (prior to the last database update) cannot be queried with this tool, that is, you cannot see what the information used to be before the latest change was made.
Compliance data from discharge monitoring reports (DMR) are not available with this tool. The Data Viewer only reflects the state database for water quality permits. It does not connect to EPA federal data systems. The EPA database may show some discrepancy with the state system at any point in time. TDEC does its best to maintain consistency between the federal and state systems, but this is now a manual process and corrections take time.
Data Entry and Data Error
- The terms 'active,' 'inactive,' 'terminated,' 'incomplete,' and 'expired' reflects particular permitting language used by the Division of Water Resources for specific situations.
- An ‘active’ permit is one that is in effect.
- A permit is ‘inactive’ if the need for permit tracking is not necessary, such as when the permitted activity is suspended. Thus, if a permit holder stops activity but may re-start in the future, the permit may be set to ‘inactive’ and re-set to active later.
- A permit may be ‘terminated’ for cause at any time by the division. In that case the authority for the permitted activity is stopped. Once terminated, the permit becomes inactive in the database.
- If the permit is shown as 'incomplete,' there has been a request for permit action that requires additional information. The issued permit may be in effect (check to see if it has an issue date) but division staff are waiting for more information before the application materials or request for permit change can be resolved.
- An ‘expired’ permit date is the closing date for the permit period. The Division’s goal is that permits be promptly re-issued so that one permit period follows on another. There are times when this is not possible. A permit that has passed its expiration date remains active where an application is received before the expiration date. The conditions for the expired permit remain in effect until the permit has been re-issued. Expired permits that have not been applied for become defunct and are inactive in the database.
